Ok – I had a look at your site – what problems do you have exactly? Can yoou upload feature images via post/page editor? If yes please upload some sample content, and/or describe your problem. Does the slideshow work? If not please deactivate all plugins and activate them one by one so because maybe it’s a javascript conflict.

Hey I have the same issue.. I have uploaded photos to my ftp server, when I add photos in the Featured Images and link through URL (and it gives me a GREEN tick mark on the left) I can not see the image appearing in my article and nor a thumbnail in the Featured Article menu bar.

You need to upload the images to your media gallery and select one as featured image. Then you click on the plus symbol to create another featured image. It’s currently not possible to use an url to an external image.
